I want to ask if cd laser is repairable or not. I have a car stereo. So here it is, it is working when suddenly it stopped reading and saying "error 04". Since i knew some electronics, i opened it and saw that the laser is very eak. I adjusted it at the back but still its not working. The light is very weak whatever i do. If i buy this part will cost me more so im asking if it is repairable.. Thanks.
